TYPE-WRITER Specification of Letters Patent.

Appltcatton filed April 7.

To all whom it may concern:

lie it known that LLoris lC. li.\l.'l7.l.ll\', a citizen of the l nitcd States residing in \Vasbingtom District of t'olumbia. have invented a new and useful improvement in Type-\Vriter Attachments, of which the following is a description.

The invention relates to a device on which the ty ewriter is mounted for the purpose of 1 prov! ing resilience thereto, to absorb the sound attendant upon operating a typewriter, soften the touch on the keys, and l eliminating the cutting element of the typ bar on the platen, and is an im )rovcment oi the application of Edwin lla ltzley. Serial Number 381,708, filed July l. 1 07.

It consists more particularly of a locking device whereby the typewriter may be locked to the said attachment.

'It also consists of a means for automatically locking the machine to thedevice. Also of a sprin base or bed for the typewriter to rest on. ISO of an adjustable hook, pivoted to a cup on the rear member of the attachment, in which the rubber foot of the typewriter rests.

It also consists of the attachment adjustable totypewriters of different widths. Als of other new and useful features which will be set 'forth and claimed;

Makers of typewriters have not only made .their typewritersrigid but heretoforehave considered it necessary to fasten the typewriter rigidly to the desk in which it is madc to disappear. This rigidity not only made a drum of the desk and magnified the noise of the typewriter, but it also hardened the touch of the t pewriter and gave a cutting quality to die stroke of the typebar. It is well known that in boiler punching or die stamping, if there is the slightest give or resilience under the punch, it will dent or bend the metal but not cut it. So, when the typewriter is rigid, the hammer blow of the typebar is a cutting blow to the ribbon and a shock to the machine, thereby de; creasing the life of the ribbon and typewriter, but when mounted 1'esiliently.-tlie effect. of the blow is to deliver pressure but not the. cut and shock.

' an elevation of the front. attachment, showing the locking mechanism. Fig. l is a front elevation of the locking mechani m i shown in Fig. Fl, and in its first or automat c locking position. Fig. 5 is the same as Fig. l. but in its second or pressure locking posii tiou. Fig. (5 shows the detail construction I of Figs. 4 and 5. Fig. 7 is a typewriter frame with my removable locking lugs at. tachcd thereto. Fig. 8 shows the lug before the strap is bent over. Fig. .l is.thc same as Fig. 8. but after the strap is bent orcr. Fig. 10 is a locking lugattachahlc to the -typewritcr frame by a screw underneath.

l I Fig. II is an elevation of a single loop form a of the invention and is a modification of the preferred double loop form. Fi 152 is an elevation of a single loop form of the inventhcinframes widely that have found it necessary to make my attimhn'icnts adjustable and pro-vidc a form ofconstruction. lll combination with a locking lug, which will appl to all machines. In the front attachment. the frame of the typewriter rests on the spring bed. in loop fol-uni. and 3. which is bent so that the outer side extends upward to form the slotted locking standard t. best. seen in Fig. The l0l .3 in this tandard is to receive the locking lug hcrciuaftcr described. outwardly at U and T to provide a wide opening to guide the locking lug into the slot. hole 8 is panelled in the lower nirt of thestaiulard. The hook i is lllVUlOt to the standard ,-I throu' h thc holes 8 and by the. pivot 11. The resilient. attacluncnt is made by forming a loop at each end, the outer leg 12 of which i longer than the nnci' one 133, as shown. The lower end 14 of the leg 1'. is-bcnt outward at right angles to form a foot having a screw hole 15 f through wh ch the attacluncut is fastened to In the drawings, Figure 1 is a perspective I thedesli. the standard l is riveted to the of a frame of ,a typewriter with its top broken off, mounted on a pair of my attachments. Fig. 2 is an elevation of the rear attachment showing the feet cups and the adjustable hooks pivoted thereto. Fig. 3 is uttaohnuait li near to the resilient. loop as shown. hole 16 through the attachment; receives the lower end of the spring 17, the

, to press the hook 9 forward to its lock-mg 'lypewriters vary in the construction of This slot is hcvelcd upwardly and ltlt) upper end of which rests against the pi 18 a In Fi position. The hook 9 is provided with a thumb extension It) and the automatic hook end .20 and the binding inner hook position 21. It: top side i inclined forward and downward so that vertical (.lt'WIHYt'H'tI preasure of a big, as indicated in dotted lines 23, would 'spring it back out of the wa so that.

the lug could pass down into the s ot 5 and oet-u )v the position shown at .24. The hook 'Ottt automatically spring over the lug and rest against it at its swell 25 and thereby automatically latch the lug in the'slot 5.

I provide a locking lug for all the t pewriters. It is attached to the frame 0 the t \'pcwriters in different ways, and, therefore, is provided with different means of attaching it to the frame. In Fig. 7 is shown a strap :26 bent over the typewriter frame, and having the lug 27. In Fig. 8 the strap is shown before the t of the strap is bent down. Fig. 9 shows it after it is bent down. 10 the strap to which the lug is rivete has a screw hole through which it is fastened to the bottom of the frame of the typgnvriter.

0th the attachments I! and C are made of two pieces to slide one over or on the other, and provided with the slots 29 and the screws 30 whereby the attachment may be lcugthenedor shortened. The sides of the portion of the attachment between the loop ends are bent down or channeled in order to give them rigidity. Reliance for resiliency is mainl upon the resilient loops at the ends of tie attachments. On the rear attachment I provide foot caps 31 and 32 and to these are pivoted the hooks 33 and 34, which are connmsed of two parts, made slidable on each other and fastened so that they can be lelggthened or shortened, adapting them to di erent typewriters having frames of ditl'erent widths. In operation these hooks are thrown back, the rear feet of the typewriter then dropped into the caps 31 and 3-2 and the front of the typewriter low-- ercd until the lugs 27 strike the cam or inclined top of the books 9 at 23. The further descent of the machine carryin the lugs 27 causes the lugs 27 to force the looks back out of the wa when the lugs drop to the bottom of the s ot 5 and the hooks spring hack over the lugs until they rest against the lugs at the swell 25. hen pressure against the. hooks will force the spring base '3 and 3 down until the lugs s rin into the inner lot-king position 21 and t ltltiy tightly hold the typewriter to the attachments. The

rear hooks Iii-l and 3t may-now be thrown forward and forced over-the frame. There is tllllt'ltllt. give to the rubber feet and the attm-hment to give a spring grip to the hooks on the frame.

In Fig. 11 I show a modification of the invention, consisting of a short. loop to which the locking mechanism hcreinhefore described is attached. It is individual to one side of the front of the ty writer. Another one like it on the opposite side is individual to that side and completes the front equipnu-ut. In the. double loop form. the width of the device has to be ada ted to tltt'll of the ditfercut ty writers, w ile in the single loop this is o viated.

Fig. 12 la a single loop with a cup attaehed thereto to mceive one of the rear feet of the typewriter and in individual to it, while anothcrlko it it! individual to the other rear foot.
